FINALLY got my 622 YAY
Had to beg and plead with the CSR as my install was set to sometime in April to turn it on.
She told me she couldnt and that if she did I would lose my 90 day install warrenty and be CHARGED for the install.
I told her I already paid my 299 so I wont be charged anything...but I could care less about an install warrenty. I could do the work myself if they would just give me the 1000 and a DPP44
Anyway here is where it gets funny.
They end up activating it after some serious pleading and begging and then pulled up another install date. Guess what... it moved up to this thursday from Apr 4th. What a crock they were telling me saying the install would move even more forward in the future. Anyway im super happy. And without the 1000 I still get Discovery HD, Universal, TNTHD and ESPNHD till Thursday.
-------The Review--------
The OTA Tuner
I have to put this at the top of the list. If you have any doubt or question to upgrade, this alone is worth the price of admission.
The OTA tuner kills the one built into my Hitachi. I can pick up stations I could never pick up before with an antenna just sitting on top the entertainment center. I got 3 of my locals pegged at 100 percent!
HDMI vs Component
Found out by buying an HDMI cable that my TV wont pass DD 5.1 through to my receiver. Either that or the 622 wont pass DD 5.1 through the HDMI cable. My TV's optical out to my audio reciever is only doing DD 2.0 with the 622 when watching 5.1 content.
Since I cant get DD 5.1 through the TV to my audio reciever I decide to just run an optical cable from the 622 to the reciever directly and solved that problem.
That got me thinking. What is the PQ on HDMI vs Component? For me I saw ZERO difference in picture quality. That HDMI cable is going back to the store for a refund!
Differences from a 721 to 622
First thing that stuck out like a sore thumb is that I really used that Red button on the 721 to buffer another channel while watching another. Came in real handy when watching 2 shows and swapping during commercials.
After that let down I have to say this box is light years ahead.
First off I got my first experience with Dish Pass and the ability to only record new episodes. An added bonus is that if the show shifts in time it will record it. For example. 24 is on 9pm Monday's. Next week its on for 2 hours from 8-10pm. The 622 noticed and immediately switched the timer to accomidate! That is nice.
The new HD guide is handy but I went back to the regular guide for now because looking at 5 hours of content is sensory overload. I will probably switch back later.
Dish Home now matches what my 508's show. I kind of liked being able to access the weather without going into Dish Home on my 721. That feature will be missed.
Box is lighter and narrower than my 721. Amazing technology considering what this beast can do.
Picture Quality and Audio Dropouts
Im going to throw in a host of things in this section.
First off the PQ seems softer then the 721. I dunno why. I know there is some upconversion going on with the box in SD but even HD feels a little soft. Maybe I am seeing the HDLite effect because I didnt really notice it on 24 or CSI: Miami Over the Air.
in the first 24 hours of owning it I have managed to really upset the device. I have had the Picture stop working and have only audio. Also I notice if I am looking at the guide and someone calls in, the picture will go off when it displays the caller ID information. This doesnt happen when I am just watching a program. Only when I am in the guide.
I had audio problems with popping when using the HDMI cable. I fixed that by not using the cable

. No audio problems when using optical.
Found audio out of sync when watching a program from DVR and fast forwarding around in it. I fixed it by using the 5 sec rewind button and it sync'ed up.
Managed to lock up the box a couple of times by chaning the HD output settings. Changing from 1080I and 720p playing around. No big deal as I dont see using this much after I settle in with the unit. Fixed by holding in the power button on the front of the unit.
Heat and Fan issues
If you dont have a well vented area to put the 622, dont bother getting one. This thing gets warm! However, I only think its getting slightly warmer than my 721 in the same location. The area I have has plenty of room to vent on both the left and right side.
I have heard the fan spin up one time for about 2 seconds. I dunno why it did this but I think I was fiddling with a setting in the unit so I probably found a "feature." If you own one of these things you know that fan is LOUD when its at full speed. Good news is that as long as its vented it should never spin up.
Another thing that I know for certain that will cause a fan spin up is when the unit is updating guide data. No big deal because the time for the program guide update can be changed easily in the menu.
Conclusion
I cant wait for the install to get the other channels. This device is by far more advanced than anything I have seen from Time Warner in my area and can be configured as a true multimedia center for the whole house.
This is a home run for Dish IMHO. If you dont have a 622 get one. It doesnt disappoint!
